- 1VertebraeCervical: C1-C7
Thoracic: T1-T12
Lumbar: L1-L5 - 2CurvatureCervical Lordosis: 2 degrees
Thoracic Kyphosis: 1 degree
Lumbar Lordosis: 2 degrees
Sacral Kyphosis: 1 degree - 3Abnormal CurvatureExcessive Kyphosis: more curve at thoracic
Excessive Lordosis: more curve at lumbar
Scoliosis: lateral curve of thoracic - 4Typical VertebraeSpinous process: posterior
Body: anterior
Transverse process: lateral
Vertebral arch: formed by lamina and pedicle
pedicle: between body and transverse process
intervertebral disc: between vertebrae
intervertebral foramen: space between vertebrae - 5Cervical VariationsShort spinous process, horizontal, bifid
Transverse foramen: hole for vertebral artery
A shaped - 6Thoracic Variationsvertical
costal facet: ribs articulate with vertebrae
W Shaped - 7Lumbar Variationsshort and chunky
Short, blunt spinous process
T shaped - 8Atypical VertebraeAtlas: no spinous process or body, allows up and down movement
Axis: vertical dens and body for C1 and C2, allows for side to side
Sacrum: 5 fused vertebrae - 9Cervical RibC7 has a transverse process that resembles a short rib
- 10Bony LandmarksC7 and base of neck

Medial attachment: C7-T4
Lateral attachment: mastoid process
Nerve: Dorsal spinal
- 19Illiocostalis, Longissimus, SpinalisLateral: Iliocostalis
Medial: Spinalis
lateral flexion, extension of vertebral column
inferior attachment: thoracolumbar fascia and iliac crest
superior attachment: lateral ribs, medial spinous process
Nerve: Dorsal spinal
- 20Semispinalis4-6 vertebral segments
extension
inferior attachment: transverse process C4-T5
Superior attachment: between superior and inferior nuchal lines
Nerve: Dorsal spinal
- 21Multifidus2-4 vertebral segments
rotation and extension
inferior attachment: sacrum and transverse processes of lumbar through cervical

- 23Fasciasuperficial: deep to skin, contains subcutaneous tissue with fat
Deep: surrounds skeletal muscle, separates compartments, wraps around muscles
Thoracolumbar: deep fascia, wraps around multiple muscles
